U.S. Air Force Tech. Sgt. James Williams, assigned to the South Carolina Air National Guard’s 169th Fighter Wing, inspects the actuator from one of their F-16 Fighting Falcons during Arctic Challenge Exercise 2019 at Kallax Air Base, Sweden, June 4, 2019. The damage to the actuator and the leading edge flap will require a total wing replacement, a very complex repair normally accomplished at home station or at depot where parts and specialized tools and equipment are readily available. ACE 19 is a Nordic aviation exercise that provides realistic, scenario-based training to prepare forces for enemy defensive systems. U.S. forces are engaged, postured and ready to deter and defend in an increasingly complex security environment. (U.S. Air National Guard photo by Senior Master Sgt. Edward Snyder)
